Will I get VAC banned on MW2?

Ok, so I downloaded the MW2 Liberation mod about 4 days ago. The only thing I did was load the game with liberation. Never played any games while using it (pvt. match, public). I loaded the game with it, and quit. That's it. Will I get banned, seeing as I never tampered with any of the files? The VAC by-passer was on too. Thanks.
